2 Acknowledgements Mr. Jeff Dailey, NSL, Chief Engineer, NASA INSGC and ElaNa 5 Programs: Launch Opportunity Air Force Research Labs (KAFB): Funding and Analysis Students: TSAT Student Instrument Suite (ASEE Publications) Globalstar Management, Engineering, Marketing, and Legal Taylor University general TSAT student support 2

3 GlobalStar Radios GlobalStar Constellation ($2B ) 32 plus LEO Satellites (1400 km) Provides global data and voice services for ~ 300,000 customers Used primarily for infrastructure/wildlife monitoring Oil Rigs and Gas pipe-lines Shipping Containers and Endangered animals EyeStar developed by NSL for high altitude ballooning (EyePod) NSL has flown over 300 HARP balloon launches with 99.5 data/recovery Data links via the GlobalStar network Code division multiple access (CDMA) Payload commanding Data downlinks Recovery tracking (with GPS) 3

4 Globalstar with EyeStar Simulations ( Bent Pipe distributed data downlink) 4

5 TSAT Taylor, Technology and TEST Satellite Taylor University 2U Spacecraft Demonstrating the EyeStar Radio (Beacons only) Plasma Data Started in 2012 as a Senior Capstone project TSAT was launched on 4/18/14 (1 Week ago!) SpaceX CRS-3 NASA ElaNa 5 Built by Taylor University and Near Space Launch TSAT launched 1 week ago on CRS 3 5

6 EyeStar Quality CubeSat Comm. Link the Edge of Exploration Professional demanding missions (Discovery) Reliable and seamless data link Many comm. systems associated with CubeSat failures and require significant flight hardware and tracking time/cost Complements high-data rate downlinks Beacon GPS, Health, Back-up and Sample data sets EyeStar Unified Constellation Data Base 6

7 EyeStar Product Features Anytime, Anywhere Satellite TT&C > 50% of the packets transmitted by TSAT were received Estimated 98% orbital coverage for ADCS Controlled S/C Common FCC Satellite-to-Satellite License Delivered with the EyeStar Radio No Amateur bands Radio astronomy interference was eliminated by limiting the GlobalStar units to operate at MHz with a bandwidth of +/ MHz No satellite to ground license required 7

8 Anytime Anywhere Satellite TT&C ISS, 3 of 40 Globalstar footprints and five ELaNa 5 Satellites footprints 8

9 TSAT GlobalStar Demonstrations Create Global Simplex coverage map Real-time Telemetry Data received from TSAT ~11 seconds after turning on Ground station can be a laptop Data transfer via IP from Globalstar to NSL and on to end user Ground segment solution services available from NSL 9

10 TSAT Packet Count Versus Time since launch 0 Received Packets 5,000 GlobalStar releases cap on packet distribution rate 0 Time (Min) 10,000 Consistent global reception (which varies from 4/25/2014 traditional ground Near stations Space that Launch are location dependent) 10

11 Preliminary TSAT Coverage Map (now about 90% simplex packet throughput over US, Europe, Australia) Beacon Cycle 32 beacons (Five second interval) 15 minute dwell Results after 1 Week > 50% packet throughput on a tumbling satellite > 5000 packets received to date > 1 MB of telemetry Near Global Data Downlink Coverage 11

12 Plasma Temperature Demonstrated low latency space weather data retrieval (seconds to minutes) 12

13 Simplex EyeStar Features Small form factor Power Accepts 6.5 V to 20 V 200 mw Tx power Volume 44 mm x 81 mm PocketQub form factor Beacon Data Inputs TTL Data Protocol 8 Analog Inputs 8 Digital Inputs 13

14 EyeStar Product Features No deployables 2 cm x 2 cm patch for simplex 2.5 cm diameter circular patch for duplex Rapid acquisition Received the first TSAT beacons 11 seconds after turning on Not ITAR Restricted High data rates limited 9600 kbps maximum (advertised) GEARRS will investigate maximum data rate EyeStar intended to complement traditional high speed radios 14

15 Location of first Transmission after 11s Radio Turn On 15

16 EyeStar Product Features Ground station over Internet Protocol (IP) Access your spacecraft from anywhere Piggy-backs on established 2 billion dollar network Low Cost No Ground Station No tracking Proven system (TSAT/GEARRS/SHARC) For Low Data Rates: < ~ 1 cent/byte (TBD) Baseline (TBD): Retail Terrestrial Data Cost 16
